Answer:
The angle of diffraction is 13.09°
Explanation:
Given:
Wavelength of light m
Order of diffraction
No. lines per centimeter
First find the grating element,
m
From the formula of diffraction,
13.09°
Therefore, the angle of diffraction is 13.09°
Your question asks what the slope of a Position vs. Time graph represents.
Your answer would be Velocity.
The slope of a Position vs. Time graph would represent the velocity of the object.
If the slope is positive, then the object has a positive velocity ,in which it is going forward.
If the slope is negative, then the object has a negative velocity, which means that it's going the opposite direction, or backwards.
If the slope is at a "horizontal" position, this means that the object is stopped or isn't moving at all.
α=30°
F=20 N
Fh=F*cos(α)
Fv=F*cos(90-α)=F*sin(α) (vertical component of the force F)
Fv=20*0,5=10.00 N
Answer (C)
Explanation:
a. the total time taken for the journey is 50sec.
b. u=0, v=10m/sec, t=20sec.
a=(v-u)/t = (10-0)/20 = 10/20 = 0.5 m/s².
hope this helps you to solve the problem.
